It's a good documentary, but Nick Cook didnt' do his homework. For example, in the Zamora case, he claims the police officer witnessed a classice silver disk, which he Cook believes could be part of Project Silverbug.

The problem is that this isn't what the witness claimed to have seen.

Instead of a 'Classic Silver Disk', Officer Zamora claimed to have witnessed an Egg-shaped object with a red insignia on the side. Around the craft were small, child-like beings who moved fast and frightened him. When the beings saw Zamora, they quickly entered the craft and the craft took off.

The scene was investigated and there were indentation marks consistant with some sort of landing gear as well as scorch marks on the ground.

Project Bluebook investigated but the case has never been succesfully explained away, though many skeptics have tried.

Recently, a few die-hard debunkers claimed that what was witnessed was a proto-type of the Lunar Lander, but this claims has been dismissed.
